- Upgrade instructions are available for selected models on the Sony® eSupport Web site.

- The upgraded operating system must have the same Service Pack or higher included as the original Operating System on the computer.
- VAIO® computers bundled with the Windows XP Home Edition operating system may utilize the original Sony® drivers and applications with the Windows XP Professional Edition operating system. Due to the common core between the two operating systems, the same drivers and applications will work in both versions. Sony will continue to support the drivers and applications, but will not support the operating system in these cases.
- Issues may occur when installing a different language version of the operating system with the Sony® drivers or software.
- Sony does not support dual boot configurations.
- If the computer was not supplied with Recovery CDs/DVDs, ensure the Recovery Media Kit has been created before proceeding.
